Application filed November 10, 1888. Serial No. 290,435. (No model.)

To all whom it may concern.- and take a firm clutch-hold of the same, and.

Be it known that 1, HENRY G. PORTMANN, upwardly-presenting lugs (i, that clutch the of the city of Louis, in the State of Miscombined side and handle bar 7, thehandle to souri, have invented a certain new and usewhich is, as usual, bent at the rear end of said ful Improvement in Spring Teeter-Gears for side bar and integral therewith. S are the 55 Childrens z'n-riages, of which the following horizontal bearer-plates of said foot-lugs, on is a full, clear, and exact description, referwhich the side pieces are supported, and to once being had to the accompanying drawwhich they are secured by the bolts 9, that ings, forming part of this specification. pass through perforations 10 in said side To This invention relates to spring-gears for pieces, corresponding holes 11 in the bearer- 6o ehildrens carriages, the rear springs of which, plates and 12 in the axles, and are secured while acting as buoyant spring-sup iiorts to by screw-nuts 13, which screw onto the prothat end of the carriage, also provide the jecting ends of said bolts beneath the axles. means for a vertical teeter when it desired It will be seen that the said foot-clamps of 15 to soothe the child to sleep;and the invention the arch-bars, with their bearer-plates and consists in features of novelty hereinafter lugs projecting in transverse directions to fully described,and pointed outin the claims, clamp both the axles beneath and the side the device being an improvement on my inbars above in conjunction with the bolts, ventions patented January 31, 1888, No. make a firm grip-connection of said axles,

The spring is made in a double returnloop curvilinear form, having preferably a Wide loop at top and narrow one at bottom, and runs lengthwise of the carriage. The lower terminals 30 of said sprin are fastened to the spring-seats 31 at the ends of the rear spring-bar by screw-bolts 32, that pass through perforations 33 in said springs an d sprin g-arm, and are there secured by screw-nuts 34', that engage on their projecting ends.

The childs carriage is a great convenience to mot-hers and nurses when children are being taken out for an airing until the little ones get sleepy, when frequently they require a different movement to the usual movement of the carriage, nearer akin to that of the cradle, and the child in consequence has to be lifted from the carriage and carried by its attendant. One of 'the features of this invention (its rear double-fold ogee teeteringsprings) is intended to overcome that diffieulty, and by its reciprocating movement of the carriage-bed to soothe the restless child and induce it to go to sleep.

I claim as my invention 1. In a childs carriage, the combination of the arch-bar that supports the springs, the foot-clamps on the ends of said bar, and the lugs that project from said footclamps and clutch the axles beneath and the side bar above, substantially as and for the purpose Set forth. 1

2. In a childs carriage, the combination of the arch-bars that support the springs, the foot-clamps on the ends of said bars, provided with bed-plates 8, that carry the side bars, said plates integral with the foot-clamps, and the lugs that project transversely from said foot-clamps and clutch the axles beneath and the side bars above, substantially as and for the purpose setforth.

3. In a childs carriage, the combination of the arch-bars, the spring-bars seated on said arch-bars, and the double-fold ogee teetersprings 29, that couple the rear spring-bar to the bed of the carriage and provide the means of teetering said carriage-bed and of its elastic rear support, substantially as and for the purpose set forth.

4. I11 a childs carriage, the combination of the arch-bars, the foot-clamps provided with transversely-presenting lugs that clutch the axles beneath and the side bars above, the spring-bars that surmount said arch-bars, the loop-ended three-quarter elliptic spring that is secured to the front spring-bar and to the front of the carriage-bed, and the double-fold ogee teeter-sprin gs that couple the rear sprin gbar to the bed of the carriage, arranged to provide the means of teetering said carriage bed and of its elastic support, substantially as and for the purpose set forth.
